[Description] ref_dtbclk value is assigned in clk_mgr_construct, but the clks struct is cleared in init_clocks. Make sure to restore the value or we will get 0 value for ref_dtbclk in DCN31.

drm/amd/display: protect remaining FPU-code calls on dcn3.1.x

2022-04-28T21:44:02Z

From [1], I realized two other calls to dcn30 code are associated with FPU operations and are not protected by DC_FP_* macros: * dcn30_populate_dml_writeback_from_context() * dcn30_set_mcif_arb_params() So, since FPU-associated code is not fully isolated in dcn30, and dcn3.1.x reuses them, let's wrap their calls properly. Note: this patch complements the fix from [1].

This reverts commit 863fa85e6a01c8b239009825dd9de1f64d7d020a. While we were testing DCN3.1 with a hub, we noticed that only one of 2 connected displays lights up when using some specific display resolution. In summary, this was the setup: 1. Displays: * Sharp LQ156M1JW26 (eDP): 1080@240 * BENQ SW320 (DP): 4k@60 * BENQ EX3203R (DP): 4k@60 2. Hub: Club3D CSV-7300 3. ASIC: DCN3.1 After bisecting this issue, we figured out the commit mentioned above introduced this issue. We are investigating why this patch introduced this regression, but we need to revert it for now.
